Scleroza

Scleroza is a general term referring to hardening or thickening of tissues. While it can affect various parts of the body, it is most commonly associated with medical conditions affecting the nervous system. In the context of neurological disorders, scleroza refers to the process of sclerosis, which involves the formation of hardened, scar-like tissue in the brain, spinal cord, or optic nerves. This scarring, also known as gliosis, occurs when glial cells, which support nerve cells, proliferate in response to damage or inflammation.

The most well-known condition characterized by this neurological sclerosis is multiple sclerosis (MS). In MS, the myelin sheath, which insulates nerve fibers, is damaged and then replaced by scar tissue. This disrupts the transmission of nerve impulses, leading to a wide range of symptoms that can vary greatly depending on the location and extent of the lesions. Other conditions, such as amyotrophic lateral sclerosis (ALS), also involve the progressive degeneration and hardening of motor neurons. Scleroza itself is not a disease but rather a pathological process that underlies several distinct medical conditions.
